BIRTHMARKS (Nevi) Blue-Inexperienced or Blue-Grey Patch;
Mongolian Spot The Mongolian spot is a bluish splash like an ink stain with irregular borders that fade steadily into the encircling pores and skin. The mark was dubbed Mongolian as a result of it was first seen on Oriental infants. Really, any child with the tiniest diploma of pigmentation in his ancestry can have Mongolian spots.
